Abstract:
A fluid path set includes a first fluid line having a proximal end fluidly connectable to a source of a first fluid and a second fluid line having a proximal end fluidly connectable to a source of a second fluid. A flow mixing device is in fluid communication with distal ends of the first and second fluid lines. The flow mixing device includes a housing, a first fluid port provided for receiving the first fluid, and a second fluid port for receiving the second fluid. A mixing chamber is disposed within the housing and is in fluid communication with the first and second fluid ports. A third fluid port in fluid communication with the mixing chamber for discharging a mixed solution of the first and second fluids. A turbulent flow inducing member is disposed within the mixing chamber for promoting turbulent mixing of the first and second fluids.
Abstract:
Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce a product such as a biofuel.
Abstract:
The present invention concerns a stirrer system for animal cell culture consisting of a combination of at least one radially-conveying stirrer element and at least one axially-conveying stirrer element, wherein at least three stirrer elements must be present and the uppermost stirrer element is an axially-conveying stirrer element. The stirrer elements are arranged at a certain distance above one another on a stirrer shaft. A particular embodiment is a multiple stirrer system consisting of two disk stirrers as radially-conveying stirrer elements and an inclined-blade stirrer as an axially-conveying stirrer element wherein the inclined-blade stirrer is arranged above the disk stirrer on the stirrer shaft. The stirrer system according to the invention achieves among others a gentler and better intermixing in the culture of shear-sensitive mammalian cells in cell cultures.
Abstract:
A mixer body (14) has an interior bore (16) and an exterior surface. The exterior surface has a first stage (18), an intermediate second stage (22) and a third stage (20). The mixer body forms a support ring (26). The second stage has threads (28). The third stage has holes (30). Pins are secured to the support ring (36). A turbine (38) is rotatably coupled to each pin. A disk (40) has arcuate ends (42) and cut away sections (44). A cylinder (48) has a first stage (50), an intermediate second stage (54) and a third stage (52). The cylinder has an input end with a large opening (56) for receiving a pipe. The cylinder has an output end with a discharge opening (58). The second stage of the cylinder has threads (60) coupled to the mixer body. The third stage of the cylinder supports the turbines and the disk. When the mixing body and cylinder are threaded together, they form a chamber (62).
Abstract:
Es wird eine Vorrichtung (1) zum intensiven Mischen einer Flüssigkeit und mindestens eines festen oder flüssigen Additivs zu einer Dispersion beschrieben mit einem geschlossenen Gehäuse (10) und einer in einem Innentubus (11) des Gehäuses (10) angeordneten antreibbaren saugenden Umwälzeinrichtung, welche die Dispersion in eine rotierende Umwälzbewegung versetzt. Es ist vorgesehen, daß am Ende des Innentubus (11) das Austrittsende einer Sprühvorrichtung angeordnet ist, und/oder daß der Rotor (14) in einem radial außenliegenden Abschnitt Verlängerungen aufweist, die um den erweiterten Austrittsabschnitt des Innentubus (11) herumgreifen, und/oder daß schraubenlinienförmige Leiteinrichtungen (101, lila, Uli) an der Innenwandung des Gehäuses (10) und/oder an der Außenwandung des Innentubus (11) und/oder an der Innenwandung des Innentubus (11) angeordnet sind. Weiter wird ein Verfahren zum intensiven Mischen einer Flüssigkeit und mindestens eines festen oder flüssigen Additivs zu einer Dispersion beschrieben.

Abstract:
An impeller is configured by disposing a plurality of blades extending from the center toward the periphery between discs opposed to each other. Two or more fluids are introduced through an inlet provided in or near the central position of the impeller, and large quantities of two fluids are mixed uniformly and efficiently.
Abstract:
An apparatus and method are disclosed for mixing and pumping solids and fluids and includes use of a blender including: a casing defining a cavity; a drive shaft extending through a casing opening into the cavity; a slinger having an outer edge, a center, a bottom slinger surface, a top slinger surface, and a plurality of slinger blades extending upwardly from the top slinger surface, wherein the slinger is attached to the drive shaft, and wherein the height of the top slinger surface above the bottom slinger surface continuously increases from the outer edge to the center; and an impeller having a bottom impeller surface and a plurality of impeller blades extending downwardly from the bottom impeller surface, wherein the impeller is positioned below the slinger and is attached to the drive shaft.
Abstract:
The present invention relates to emulsion and double-emulsion based processes for preparing microparticles. The invention also relates to workhead assemblies for in-line flow-through mixing devices that can be used for mixing two or more fluids. The workhead assemblies can be used with the processes for preparing microparticles.
